The wireless network may be a wireless local area network. A handover of the mobile station from the first wireless network to a second wireless network may be made based upon a measured signal characteristic between the mobile station and the first and second wireless networks.

Abstract: Apparatus, and an associated method, for providing WLAN (wireless local area network) service through a fixed wireless access communication system. WLAN transceivers are fixed in position at subscriber stations of the fixed wireless access communication system. Each WLAN transceiver defines a coverage area. Through appropriate positioning of the WLAN transceivers at the subscriber stations, overlapping coverage areas are formable and between which handovers of communications with a mobile station are effectuated when a mobile station travels out of one coverage area and into another coverage area.

Abstract: TDD access equipment modified by introducing a frequency change at the normal TDD guard point, with respective downlink or uplink periods for individual subscriber stations offset to form overlapping frames. Cyclo-stationary processing, block equalization, and burst timing coordination allow the boundary between downlink and uplink portions of both frames to be set dynamically, improving spectral efficiency. Fast frequency switching within an allotted physical slot enables synchronization of time-sharing the dedicated frequencies to be maintained among subscriber stations. Duplex spacing between downlink and uplink frequencies for individual subscriber stations, combined with in-depth filtering of received signals, prevents spurious out-of-band transmission signal strength from reaching an interference level.

Abstract: A wireless communication system has a plurality of subscriber stations linked by radio with a network infrastructure coupled to a correspondent node. A call is originated at a subscriber station apparatus. The apparatus includes a call establishment message generator coupled to receive an origination indication of the call. The call establishment message generator generates a call establishment message to initiate call set-up procedures that precurse a request to establish the call between the subscriber station and the correspondent node. The apparatus also includes a response detector coupled to receive an indication of a network-infrastructure generated response to the call establishment message. The response detector detects whether the response to the call establishment message indicates that communication resources are available to establish the call. The apparatus further includes a call set-up emulator coupled to the response detector.

Abstract: Apparatus, and an associated method, for a fixed wireless access communication system, by which to initiate a call to an emergency dispatch center, or other priority call to a priority location. When communication resources are initially unavailable to permit establishment of the call, normal call set-up procedures are emulated at a subscriber station from which the call is to be originated. Communication resources are reallocated in the communication system to permit the establishment of the call and the call is thereafter established.

Abstract: On-line insertion of line replaceable units (such as circuit board cards) into a backplane of a processor shelf, a modem shelf, or a similar type of equipment utilizes at least one interface control processor card that is capable of functioning as a primary master controller to control the insertion of circuit board cards into the backplane. Circuit board cards that are newly inserted into the backplane do not automatically have access to full power, or to the buses, or to other cards in the backplane. A newly inserted circuit board card remains isolated until the primary master controller checks, configures, and authorizes the newly inserted circuit board card to operate. A secondary master controller is provided to function as the primary master controller if the primary master controller fails. An automated boot procedure is provided to enable a circuit board card to determine whether it is a master controller, and if so, whether it is a primary master controller or a secondary master controller.

Abstract: Data which must be memory equalized across a redundant, high availability system utilizing processor-based components is structured in memory segments which form data packets for a data link between active and standby components. Direct memory access is employed to copy memory segments within the active component into a queue for the data link, which transfers memory segments without utilizing the processor within the active component while automatically verifying data integrity and acknowledging successful data transfers. The direct memory access copying of memory segments to the queue may be triggered for changed memory segments by either the processor or specialized hardware within the active component, or may be run in a continuous loop sequencing through a predefined range of memory segments. The standby component may thus be kept abreast of changes to data within memory segments, such as changes to call states or resource allocation records relating to call processing.
